Karen Osei, founder of Math Vision Project

Karen Osei is a math-curriculum specialist and the founder of Math Vision Project. Years designing curriculum convinced her that how we teach a standard matters more than the standard itself — and she writes to help teachers teach for understanding.

She writes every resource herself, grounds them in real classroom practice, and answers reader questions at karen@eohc.org.
